Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Navigieren eines Kraftfahrzeugs (10) entlang einer vorgebbaren Wegstrecke (12) von einem Ausgangsort (14) zu einem vorbestimmten Zielort (16). Für zumindest eine Teilstrecke (22) der Wegstrecke (12) wird eine Fahrbahninformation zu wenigstens einem Fahrbahnzustand wenigstens einer Fahrbahn der zumindest einen Teilstrecke (22) für eine im Kraftfahrzeug (10) angeordnete Auswerteeinheit (24) bereitgestellt. Auf Empfang eines Steuerungssignals (26) zu einem Befahren der Teilstrecke (22) hin wählt eine mit der Auswerteeinheit (24) gekoppelte Navigationseinrichtung (20) die Teilstrecke (22) aus. Zunächst wird durch die Auswerteeinheit (24) zumindest ein Fahrzeugzustandsparameter ermittelt, welcher der bereitgestellten Fahrbahninformation zugeordnet ist. Anschließend wird ein benötigter Parameterwert des zumindest einen Fahrzeugzustandsparameters ermittelt und ein aktueller Parameterwert dieses Fahrzeugzustandsparameters erfasst. Mittels eines jeweiligen Vergleichs des benötigten Parameterwerts und des aktuellen Parameterwerts ermittelt die Auswerteeinheit (24) eine Fahreignung des Kraftfahrzeugs (10) zum Befahren der zumindest einen Teilstrecke (22) und erzeugt in Abhängigkeit dieser Fahreignung das Steuerungssignal (26).
(EN)
The invention relates to a method for navigating a motor vehicle (10) along a prescribable route (12) from a starting location (14) to a predetermined destination (16). For at least one subsection (22) of the route (12), road information pertaining to at least one road condition of at least one road of the at least one subsection (22) is provided for an evaluation unit (24) arranged in the motor vehicle (10). On receiving a control signal (26) to travel on the subsection (22), a navigation device (20) coupled to the evaluation unit (24) selects the subsection (22). First of all, the evaluation unit (24) ascertains at least one vehicle condition parameter associated with the road information provided. Subsequently, a required parameter value of the at least one vehicle condition parameter is ascertained and a current parameter value of this vehicle condition parameter is captured. By means of a respective comparison of the required parameter value and the current parameter value, the evaluation unit (24) ascertains a travel suitability of the motor vehicle (10) to travel on the at least one subsection (22) and takes this travel suitability as a basis for generating the control signal (26).
(FR)
L'invention concerne un procédé de navigation d'un véhicule automobile (10) le long d'un itinéraire (12) pouvant être prédéfini à partir d'un point de départ (14) jusqu'à une destination (16) prédéfinie. Pour au moins une section (22) de l'itinéraire (12), une information de chaussée se rapportant à au moins un état d'au moins une chaussée de ladite au moins une section (22) est fournie pour une unité d'évaluation (24) disposée dans le véhicule automobile (10). Suite à la réception d'un signal de commande (26) ayant pour but un parcours de la section (22), un système de navigation (20) couplé à l'unité d'évaluation (24) sélectionne la section (22). Tout d'abord, au moins un paramètre d'état de véhicule est déterminé au moyen de l'unité d'évaluation (24), lequel paramètre est associé à l'information de chaussée fournie. Ensuite, une valeur requise dudit au moins un paramètre d'état de véhicule est déterminée et une valeur actuelle de ce paramètre d'état de véhicule est détectée. Au moyen d'une comparaison respective de la valeur de paramètre requise et de la valeur de paramètre actuelle, l'unité d'évaluation (24) détermine une aptitude du véhicule automobile (10) à parcourir ladite au moins une section (22) et produit le signal de commande (26) en fonction de cette aptitude à la conduite.
